Calibrachoa plant named ‘USCAL1413-8’

ABSTRACT

A new and distinct cultivar of  Calibrachoa  plant named ‘USCALI413-8’, characterized by its compact, mounding and outwardly spreading growth habit; numerous orange-colored flowers with red-colored centers; and good garden performance.

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘USCALI413-8’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa, botanically known as Calibrachoa sp. and hereinafter referred to by the name ‘USCALI413-8’.

The new Calibrachoa is a product of a planned breeding program conducted by the Inventor in Hikone, Shiga, Japan. The objective of the breeding program is to create new Calibrachoa cultivars with uniform plant habit and attractive flowers.

The new Calibrachoa originated from a cross-pollination made by the Inventor on Apr. 17, 2004 in Hikone, Shiga, Japan of a proprietary seedling selection of Calibrachoa sp. identified as code number CJ04-23, not patented, as the female, or seed, parent with a proprietary seedling selection of Calibrachoa sp. identified as code number CJ04-22, not patented, as the male, or pollen, parent. The new Calibrachoa was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Gensingen, Germany on May 24, 2005.

Asexual reproduction of the new Calibrachoa by terminal cuttings in a controlled environment in Gensingen, Germany since May 25, 2005 has shown that the unique features of this new Calibrachoa are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar USCALI413-8 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘USCALI413-8’. These characteristics in combination distinguish ‘USCALI413-8’ as a new and distinct cultivar of Calibrachoa:

-   -   1. Compact, mounding and outwardly spreading growth habit.     -   2. Numerous orange-colored flowers with red-colored centers.     -   3. Good garden performance.

The new Calibrachoa can be compared to plants of the female parent selection. Plants of the new Calibrachoa differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Calibrachoa are not as upright as plants of         the female parent selection.     -   2. Plants of the new Calibrachoa and the female parent selection         differ in flower color as plants of the female parent selection         have apricot orange-colored flowers.

Plants of the new Calibrachoa can be compared to plants of the male parent selection. Plants of the new Calibrachoa differ from plants of the male parent selection primarily in flower color as plants of the male parent selection have yellow-colored flowers.

Plants of the new Calibrachoa can be compared to plants of the cultivar USCALI413-4, disclosed in U.S. Plant patent application Ser. No. 11/978,129. Plants of the new Calibrachoa differ from plants of the cultivar USCALI413-4 primarily in flower color as plants of the cultivar USCALI413-4 have yellow-colored flowers with red-colored centers.

Plants of the new Calibrachoa can be compared to plants of the cultivar Sunbelfire, disclosed in U.S. Plant Pat. No. 16,684. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Calibrachoa differed from plants of the cultivar Sunbelfire in the following characteristics:

-   -   1. Plants of the new Calibrachoa flowered earlier than plants of         the cultivar Sunbelfire.     -   2. Plants of the new Calibrachoa had larger flowers than plants         of the cultivar Sunbelfire.

Plants of the new Calibrachoa can also be compared to plants of the cultivar KLEC03083, not patented. In side-by-side comparisons conducted in Gensingen, Germany, plants of the new Calibrachoa differed from plants of the cultivar KLEC03083 in the following characteristics:

-   -   1. Plants of the new Calibrachoa flowered earlier than plants of         the cultivar KLEC03083.     -   2. Plants of the new Calibrachoa and the cultivar KLEC03083         differed in flower color as plants of the cultivar KLEC03083 had         apricot orange-colored flowers.
